"I'd love that-- I like lace? A lot." People are never really terribly surprised about how fussy Ilde is about her clothing, for some reason; she likes Penelope's designs, likes having pieces made for her, and given the opportunity to add lingerie to what's available there, well, she'll happily take it. "Garters and that kind of thing, like this-"

It may not be strictly necessary to hitch her dress so Penelope can see the candy-pink lingerie she's wearing underneath it, specifically the garter at the top of her (seamed) stockings, but if she is going to do something like that in public, this seems like the right place for it.

(Nice tattoo.)
